First of all:
you NEED to include code. I can't help you fix anything if I don't know how it's broken.

Second:
Where are you getting input from? How does your script know what to put for title and content.

my best guess to generate what you are looking for would be:

<?php
$title[50]=array(1=>'This is the story title');
$content[50]=array(1=>'This is where the content goes.\As you can see, linebreaks are defined by a backslash.\\Double linebreaks by two.');
$audiotitle[50][10]=array(1=>array(''));
$audiosource[50][10]=array(1=>array(''));
for($story=1;$story<50;$story++) {
echo "[Story".$story."]\r\nTITLE=".$title[$story]."\r\nContent=".$content[$story]."\r\n";
for($audio=1;$audio<10;$audio++) {
echo "AUDIO".$audio."_TITLE=".$audiotitle[$story][$audio]."\r\nAUDIO".$audio."_SOURCE=".$audiosource[$story][$audio]."\r\n";
}
}
?>

The previous poster had the wrong slash in the newline definition, try this:

<?php
$newline=array("\r\n","\n","\r"); //If you know which new line the page is giving you, you can replace it, but I don't remember which is the default
$somecontent = str_replace($newline,'\\',$somecontent); // notice the single quotes instead of the double quotes
?>

I edited the solution to move the "\r\n" to be first in the array. That fixes the problem.

Here's my test script:

<?php
$content = "And if ever there is a linebreak\r\nJust like that one\r\n\r\nAnd that one. A backslash will magically appear instead of an actual linebreak.";
$newline=array("\r\n","\n","\r"); //If you know which new line the page is giving you, you can replace it, but I don't remember which is the default
$content = str_replace($newline,'\\',$content); // notice the single quotes instead of the double quotes
echo $content;
?>

If you do use single quotes, only use one \ rather than 2, since double quotes render \\ as \ and single quotes don't render anything

<?php
$newline=array("\r\n","\n","\r"); //If you know which new line the page is giving you, you can replace it, but I don't remember which is the default
$somecontent = str_replace($newline,'\',$somecontent); // notice the single quotes instead of the double quotes
?>
